Azure IaaS (Infrastructure as a service) Technologies

Azure IaaS provides scalable, on-demand infrastructure components such as virtual machines, networking, and storage—ideal for migrating workloads or building custom environments.

1. Virtual Machines (VMs)

• Provision Windows or Linux VMs in minutes
• Choose from Standard, Spot, or Reserved instances
• Supports custom images and VM Scale Sets
• Integrates with Azure Monitor and Defender

2. Virtual Networks (VNet)

• Private IP space for Azure resources
• Subnets, route tables, and network security groups
• Supports peering, VPN Gateway, and service endpoints
• Enables hybrid connectivity and segmentation

3. ExpressRoute

• Private, dedicated connection to Azure (not over public internet)
• High bandwidth and low latency
• Ideal for compliance-sensitive workloads
• Supports failover and redundancy with BGP routing

4. Azure Storage

• Standard Storage: Cost-effective for general workloads
• Premium Storage: High-performance SSD-backed storage
• Supports blobs, files, queues, and tables
• Geo-redundant and zone-redundant options

Example Scenario

You're deploying a secure web app:

1. Create a VNet with subnets for web and DB tiers
2. Provision VMs with Premium SSDs for performance
3. Connect on-prem via ExpressRoute for compliance
4. Store logs and backups in Standard blob storage

Result: A scalable, secure, and high-performance infrastructure with hybrid connectivity and cost optimization.
